Molecular reactivity of thiolate-protected noble metal nanoclusters: synthesis, self-assembly, and applications

Abstract

The interactions/reactions of thiolate-protected noble metal nanoclusters with diverse ions, molecules and other metal nanoclusters have been deciphered.

Master key to coinage metal nanoclusters treasure chest: 38-metal clusters

“…Metal nanoclusters with well-defined chemical compositions and intuitive atomic arrangement structures are novel nanospecies with potential applications. 128–130 The quantum size effect, large specific surface area and high stability are excellent properties that facilitate the application of metal nanoclusters in catalysis. Thanks to the precise structure of the atoms, the location of the catalytic sites can be deduced at the atomic level, providing an opportunity to explore the structural, size, and ligand effects on catalytic reactions.…”

Catalytic Conversion of C 1 Molecules on Atomically Precise Metal Nanoclusters

“…To date, significant achievements have been made toward the atomically precise metal nanoclusters in terms of synthesis, characterization and structure-reactivity relationship, and the relevant progresses can be summarized in recent reviews. [13][14][15][16][17][18][19][20][21][22][23][24][25] However, less summary and perspective have been made in the C 1 transformation catalyzed by metal nanoclusters. In this review, research processes of nanoclusters for C 1 conversion are highlighted, including thermal-driven reaction processes, such as CO Au 25 (SNap) 18 and Au 25 (PPh 3 ) 10 (PET) 5 X 2 and the large ligand steric hindrance of Au 25 (PPh 3 ) 10 (PET) 5 X 2 .…”

Importantly, it was inferred that the enhanced activity after the induction period (oxygen pretreatment) was caused by the partial removal of ligands prior to the reaction.…”

“…Jin et al further explored the ligand effect in CO oxidation. 32 The intact Au 25 (PET) 18 nanocluster on CeO 2 rods (fresh catalyst) was unable to adsorb CO.…”

Qualitative and Quantitative Analysis of Tumor Cell Invasion Using Au Clusters

“…To tackle this issue, inductively coupled plasma mass spectrometry (ICP-MS) has been employed in the biological field to detect metal-labelled biological proteins due to its high sensitivity and accuracy [ 29 , 30 , 31 ]. In recent years, metal clusters with ultra-small size, unique fluorescent properties, precise molecular formulas, and exhibit better good biocompatibility that has been attractive to the analytical chemist [ 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. In 2014, Liu et al constructed a silver cluster containing three silver atoms that could label the immunoglobulin M (IgM) on the surface of Ramos cell membrane with a green fluorescent, and the IgM could be quantified by ICP-MS [ 29 ].…”
